[PATCH v2 09/16] btrfs-progs: rescue chunk-recover: use global verbose option

[Anand Jain <anand.jain@oracle.com>]

Transpire global --verbose option down to the btrfs rescue chunk-recover
sub-command.

For example: Both global and local verbose options are now supported.
 btrfs -v|--verbose rescue chunk-recover
 btrfs rescue chunk-recover -v

v2: Use new helper functions and defines
     HELPINFO_INSERT_GLOBALS, BTRFS_BCONF_UNSET, BTRFS_BCONF_QUIET
     bconf_be_verbose(), bconf_be_quiet()
    Drop verbose argument in init_recover_control()
